SPECIFICATION forming part of. Letters Patcnt No. 293,120, datedFebruary 5, 1881.

l application filed August 30, LEl. (No mrdel.)

To all who/72. it vim/y concern:

Be it known that I, STEPHEN D. Tuonnn,

citizenof the United States, residing in the eity of New York, county ofNew York, and

'. State of New York, have invented certain new and useful Improvementsin Sheet-Delivery Apparatus for Printing-lllaehines, fully de-' scribedand represented in the following speci tion, say, ofhalf-sheets, anotherof whole sheets, and a third one composed of two half or whole sheets,collected and folded together. The invention consists in a primarysheetmanipulating apparatus, which operates upon thesheets received byit, to either simply guide sheets onward, to collect two or more sheetsand guide them onward, or to fold single or collected sheets andguidethem onward, with which is combined a secondary sheet-ma nipulating apparatus and interposed change gearing, whereby theconstantly-maintained speed of the primary apparatus may be transmittedand reduced, so that the secondary apparatus shall run only at therequired speed, determined by the product received from the primaryapparatus.

The invention also contains other combinations of parts and devices,hereinafter specifieally described and claimed. W This inventionisillustrated by the accompanying drawings, in. which Figure 1 is asideelevation, Fig. 2 a longitudinal sectional elevation, Fig. 3 a planview, and Fig. 4 an end elevation, of a machine with the mechanismsadjusted to fold and deliver twopage or half sheets. Fig. 5 is a sideelevation, illustrating the machine adjusted to fold whole or four pagesheets. Fig. 6 isa side elevation, with theframe-work removed, of thesame machine,

having its mechanisms adjusted to collect and fold two full or four-pagesheets. Figs. 7 and S are side elevations, Fig. 9 a plan view, Fig.

10 an end elevation, and Fig. 11 a longitudinal The cutting-cylinders'2021 (shown for the.

purpose of rendering the description clear) belong, as is wellunderstood, to the printingmachine, said cylinders being, as iscustomary, of the same size as the type-cylinder, or amultiple thereof.In the figures of the drawings referredto they are supposed to be of thesame size as the type-cylinders, and the male cylinder is provided atopposite points withtwo cutting-blades, 10 11, one of which is adaptedto be removed fromits holding-socket, while both may be constructed soas to entirely or only partially sever the web of paper widthwise, asmay be desired. therefore divide the web ihto whole or fourpage sheets,and into half or two-page sheets. These cutting-cylinders are gearedtogether by toothed wheels 101 102, so as to revolve in unison, and willbe driven by gearing connecting with some properly rotating shaft of theprinting-machine. The printed web from the printing-machine, in passingthrough these cutting-cylinders, is severed or partially severed intowhole or half sheets, as the case may be, and thence is guided to thedelivery apparatus by means of tapes 22 23, which convey the same ontothe rotating carrierA of the primary mechanism of said apparatus.The'upper set, 22, of thesetapes are stretched from pulleys 33 over theupper portion of the carrier A, thence between the pulleys or groovedrollers 40 41, between the pulleys 48 49, over the roller 50, under thepulleys 58, and return thence over the pulleys 59 73. The under set, 23,of these tapes are stretched from the pulleys 34, and return overpulleys 7 4.

The pulleys 33 34 are set just in advance of the cutting-cylinders, andthe tapes 22 23 run lightlytogether in a direct line to the periph cryof the carrier A, and the space between the pulleys 74, where the tapes23 return, and the surface of said carrier A is spanned by conductors75. A third set of tapes, 24, are

stretched from the pulleys 7 6 over an adjust- Such cutting-cylindersmay a ing-roller, 77, and return over weighted pulleys 78. The roller 77is hung in arms 80, projecting from a rock-shaft that is actuatedthrough a rock-arm, 81, and a rod, 82, from a cam-slot, 83, in thecam-wheel O. This cam is properly shaped, so that it will cause saidtapes at suitable periods of time "to be raised into contact with theunder surface of the earrierA, as in Fig. 6, and tobe removed from suchcontact, as in Fig. 2, the pulleys 7 8 being hung on weighted arms, toimpart suitable tension to said tapes in all positions of theirmovement. The tapes 22 23 are all driven from a toothed wheel, 103, onone end of the shaft of the carrier A, with which a pinion, 90, on thegrooved roller or pulleys 40, and a pinion, 91, on the shaft of thepulleys 76 meshes, the latter pinion gearing with a pinion, 92, on theshaft of the pulleys 74. The surface speed of these tapes, as well asthat of the carrierA, is rendered slightly greater than that of thecutting eylinders 20 21 by reason of the relatively greater diameter ofthe carrier A over that of the cuttingcylinders, which carrier is causedto make turn for turn with said cutting-cylinders through a train oftoothed wheels, 104 105 106 107, the latter of which is on a shaft, 55,which extends across the machine, its wheel 107 meshing with the wheel108 011 the shaft of the carrier A. The faster" movement of the carrierA causes the travel of the sheets nipped upon its surface by the tapes22 to be accelerated,

- so as to disconnect such sheets from the web, if only partiallysevered therefrom, and in all cases to advance the detached sheetrapidly enough to provide a working-space between succeeding sheets.\Vhen both cutters 10 and 11 are adjusted in the cylinder 20,the webwill be divided into half or two-page sheets, 'and as the distance fromsaid cuttingcylinders to the carrier A is arranged to accommodate thelength of whole or four-page sheets, nippingrollers 30 31 are arrangedwith the tapes 22 23, so as to nip, carry forward, and detach the firsthalf-sheet from the web while the succeeding'one is yet nnsevered, as isillustrated and explained in Patent No. 197,694, granted to me November27, 1877.

The nipping-roller 31 is mounted in the frame-work, so that itsperiphery is in direct alignment with the tapes 22 23, as is shown bestin Fig. 6, while the nipping-roller 30 is mounted in arms 85, thecarrying-shaft of which is provided with a rock-arm, 86, whereby saidrollers may be rocked from the position shown in Fig. 6, or out ofcontact with said tapes into the position shown in Fig. 2, where itpresses or bends the tapes onto the periphery of the roller 31, to causesaid tapes to firmly seize the paper passing between them at that point.Tension-pulleys 45, in adj ustable arms, are arranged to take up andrelieve the tapes 23, which are too short to stretch, as will the longertapes 22. This roller 30 may "be secured ineither of the above positionsby a thumb-screw passing through the-arm S6 and entering suitable holesin the side frame.

The carrier A is provided with grippers2, (see Fig. 2,) mounted, as isusual, upon a shaft j ournaled in the carrier, and provided with aT-head,one arm of which is pressed outward,

to close the grippers,by a spring-seated rod, 12,

pass thence to the secondary sheet-manipulating mechanism through thepulleys or rollers 40 41, with which curved guides 13 are arranged tocooperate, said guides being fixed on a shaft, 9, and arranged to beadjusted (See Figs. 2, 3, andinto the operative position incircumferential 1 grooves in'the periphery of the carrier A, as shown inFig. 2, where they are held by an arm, 14, that may be secured to theframework, or to be thrown out of such position, as in Fig. 5. Thecarrier A is also provided with a folding-blade (here shown to be arotating folder) consisting of a shaft to which extended blades 4 5 aresecured, one or both of which blades may be removable, or some othermeans provided for throwing one or both of them out of action, as is setforth in Patents Nos. 191,494, 197,694, and 214,066. The proper timelymovements of this rotating folder to cause one or both of, its blades toenter the sheet on the carrier A into the nip of the rollers 40 41 iscaused by any of the means set forth in Patent No. 191,494, May 29,1877,- and now so well understood in this art as to need no specificillustration and description here. The purpose of this secondaryapparatus is to fold the sheets received into it, and, as shown, isprovided with foldingrollers 51 52, with which coact vibratingfolding-blades 70 71. The sheets from the carrier A are conveyed intothe secondary apparatus by conducting channels or pathways, as follows:The main channel or pathway,intowhich all of the sheets are directed asthey leave the rollers 40 41, is principally composed of the uppertapes, 22, a set of under tapes, 25, that are stretched from the rolleror pulleys 41 and return over the pulleys 46, and a third set of tapes,26," that are stretched from the pulleys 47 and return over pulleys 48.The

Ito

space between the rollers or pulleys 46 47 is spanned by switches 42,which are mounted upon a shaft provided with a rock-arm, 16, that isrocked by a connecting-rod, 94, from a cam-slot, 95,- in the cam-wheel Oon the shaft 93, which cam is timed so that these switches willalternately occupy the positions shown{in,Figs. 5 and ;1, in the firstposition the sheets from it intothe firstauxiliary path way, as is shownin Fig. 2. This auxiliary a pathway is .formed, in part, by said,switches.

42, the pulleys 46, and. principally by conductors 62 63,that extendrtopulleys 68 69,

from which pulleys tapes 27 lead outward over the folding-rollers 51-52.A second auxiliary I pathway is composed, in part, of the pulleys 48 andswitches 43, butprincipallyby conductors 6O 61. The conductor 60 bridgesthe space between the pulleys 48 and the pulleys 97, over which latterthe tapes 27 after passihg the rollers or pulleys 98, are stretched, soasto continue one side of said channelto and beneath pulleys.

99, from which these tapes 27 extend outward beneath the foldin'g-blade71, andthey returnover suitable pulleys to the pulleys 68. The entranceto this auxiliary channel or pathway is betweenthe pulleys 48 49, and itis con. trolled by the guiding-switches 43, which are arranged to berocked into the position shown in Fig. 2,or intothe position shown inFig. 5.

i In the position of Fig. 2 these switches form,

in partyoneside of this cha11nel-way,whichis continued from them to thepulleys99 by the conductors 61. A third auxiliary channelway is formed,in part, by the switches 43 when in theposition shown in Fig. 5 by thetapes 22 where they. passover the switches 43, pulleys 49,-roller 50,pulleys 58, and by short 58. Thetapesand their carrying-pulleys andtapes 28, thatrun over the roller50, pass in contact with the pulleys58, and return around pulleys 57. The space between the pulleys 57 and99 is spannedon one side by conductors 64 and on the other by conductors65,the upper endsof which latter reach to the pulleys rollers of Athemain conducting channel or pathway are always driven with the samesurface speed as the carrier A, the gearing shown for thatpurpose beingthe pinions 90 89, by

which the pulleys or rollers 40 41 are geared together, an intermediate,120, a pinion, 121, on the shaft of the pulleys 46, an intermediate,

122,and a pinion, 123, on the shaft of the pulleys 47. i The tapes 22and 26 of course drive the tapes28 and the several pulleys androllersover whichsaid tapes pass with a like surface speedby frictionalcontact.

The folding i mechanisms of the secondary apparatus and thetapes27,1eading t11ereto,receive their motionfrom the shaft 93 by means of atoothed .wheel, 111, and an intermediate, 112,which1latter gears withthe pinion 113 on the. shaft of the pulley 68, which' latter piniondrives the shaft of pulleys 69 by a pinion, 114. The folding-rollers 5152 are geared together,

soas. to run in unison, by toothedwheels, as

is usual, their motion being derived} by suitable gearing from the shaft93. The foldingblades .71 are mounted upon a rock-shaft, 79', that isvibrated by motion: transmitted from the counter-shaft 93 througharock-arm,

the carrier A, to the countershaft 93, as is shown in Figs. 1 and 5.This gearing, as arranged in Fig. 1, consists of equal-sized toothedwheels 115 116, the former being secured to the shaft55, carrying theintermediate 107, whichdrivessaid carrier A. In such arrangement all ofthe mechanisms will run at a uniform speed. As arranged in Fig. 5,thetoothed wheels. 115 116 are supplanted by toothed wheels 117 118, theformer being one-half the size of the latter, by which arrangement thefolding mechanism of the secondary appara tus will be driven at one-halfthe speed ofthe carrierA and the primary mechanisms.

With its mechanisms adjusted as in Figs. 1 to 4, the apparatus will beadapted to operate upon two-page or half sheets, the dividinglines ofwhich are determined by the action of the cutters 10 11, both ofwhichare adjusted in operative position. In this arrangement thenippingroller 30 is thrown into operation, as are the guides 13. Thegrippers 2 are omit ted or thrown out of operation, and the rotatingfolder is thrown out of action. As the leading end of the web thussevered or partially severed transversely-on a line for making IOO ahalf-sheet enters into the nip of the tapes 22 23 between thenipping-rollers 30 31 it takes up the fastcr'movement of these tapes androllers, and as the division-line of the web has then passed through thepulleys 3334, the

latter will keep the leading end of thesecond half-sheet, Y, not yetsevered from the web, so that the leading half-sheet, X, held by thenipping-rollers 3O 31, may be advanced to separate such sheet from theweb and provide between its tail end and the head or leading end of thesucceeding sheet a suitable working-space, as in Fig. 2. Each sheet thusreceived by the carrier A will be guided from the surface thereof by theguides13 and pass between the rollers or pulleys 40 41 into the mainconducting channel or pathway. When the first sheet, as X, enters saidchannel, the switches 42 will have been rocked into and rest in such aposition as not to interruptsaid channel, (see Fig. 5,) such sheet Xthus being conducted through said channel and entered into the second.auxiliary channel between the rollers 48 49 under the switches 43, y

which are then fixed in the position shown in Fig. 2, this sheet X thusbeing conveyed under the roller'99 and outward on the tapes 27.

The second sheet, Y, will be led in like man ner into saidmainchannehway; but whenits head arrives at the point occupied by theswitches 42, the latter will have been rocked into the position shown inFig. 2, so as to interruptsaid channel and guide said sheet into thefirst auxiliary channel, and thence through the rollers 68 69 onto thetapes 27. These sheets X and Y will, in consequence of the distance atwhich the entrance-points to these auxiliary channels or pathways areseparated, it being aha-lf-sheets length, simultaneously enter into suchchannels, and be conveyed thereby onto the tapes 27, and by the latterbe carried outward over the folding-rollers 51 52, so as to arrivesimultaneously in proper position (against gages 66, if desired) to bedoubled into the nip of such rollers by the concerted descent of thefolding-blades 7 O 71', thus being folded in the desired direction,accord ing as such rollers and blades are related to the travel of thesheets.

For folding full sheets, as fourpage sheets, one of the cutting-blades,as 10, will be re moved from the cutting-cylinders, the nipping-rollers80 31 will be rendered inoperative, the adjustable guides 13 will bedropped down out of the grooves in the carrier A, and the rotatingfolder, with both of its blades, 4

'5, fixed in place, will be throwninto operation, and the pair of wheels115 116 of equal size, as in Fig. 1, that drives the cam-wheel O, theslot 95 of which operated the switches 42, and actuated the mechanismsofthe secondary apparatus, are changed for a pair, as 117 118, (see Fig.5,) that will make these last-named devices work at but one-half oftheir former speed. The web will now be severed or par tially severedat-distances a full sheets length apart, and each whole sheet will thenbe nipped upon the carrier A, and be advanced at anincreased speed, soas to separateconsecutive sheets a working distance apart. Each sheetthus conveyed to the carrier A will be seized by its grippers or pins,as the case may be, or

be simply held onto said carrier by the tapes 22, its leading endhanging free, and when its central part reaches the point occupied bythe rollers or pulleys 40 41, it will be creased or doubled into the nipof those rollers by the action of the rotating folder, which will beoperated as in Patent No. 171,196, December 14, 1875, so as to protrudeone of its blades, 4 or 5, at the proper time to effect such operation.During this operation the tapes 24 may continue to be rocked by theroller 7 7, for the reason that when single whole sheets are foldedtheir leading edges are drawn backward soon enough not to be nipped bysaid tapes. Each whole sheet will thus be folded transversely throughthe rollers 40 41, and be conveyed outward by the main conductingchannel or pathway, and each alternate sheet be directed by the actionof the switches 42 into one or the other of the auxiliary channels orpathways, asthe case may be, and as has been described with reference tothe small or half sheets, which, fiat or open, are of the same length asonce-folded whole sheets; but it will be observed that though thesesheets are relatively of the same length, there is'aproduct of doublethe number of half-sheets than there is or"- folded whole sheets, inconsequence of which the secondary apparatus, having but one-half thework to do, is run at one -half its'former speed. WVhen folded wholesheets are the product, there will also be more space between thesucceeding sheet-sX Y, and hence the foremost sheet, X, will arrive atand enterthe pulleys48 49 sooner than the following sheet, Y, will enterbetween the pulleys '46 and the switches 42, and hence if said foremostsheet, X, is conveyed between the conductors 61 of the second auxiliarychannel, it will arrive over the folding-rollers 51 52 out of time withthe sheet Y. To effect the simultaneous arrival of both sheets overthe'foldingrollers of the secondary apparatus, the switches 43 areadjusted, as in Fig. 5, so as to direct each sheet, as X, passing thepulleys: 48 49 upward through the longest or third auxiliary channel orpathway, intraveling through which sufficient additional travel iscaused to compensate for the greater space, and the head of said sheetis caused to arrive at the pulleys 99 simultaneously with the arrival ofthe head of the sheet Y, which sheet has been intercepted and guided bythe switches 42 at the pulley 69, whence results a concertedmanipulation of both sheets by the secondary apparatus. The length ofthese channels or pathways is such that the distance from thenipping-point of the tapes 22 on the pulleys 46 to the nipping-point ofthe pulleys 68 69, and from the nipping-point of the pulleys 57 58 tothe nip of the tapes 27 on the pulleys 99, is about equal to the lengthof a folded whole sheet, so

that the sheets may be released from the action of the faster-movingdevices the instant they are nipped by the slower-moving ones.

In manipulating double sheets, the carrier A of the primary apparatushas it mechanism adjusted so as to convert .it into a combined gatheringand folding apparatus, as is set forth in the Patent No. 191,494,whereby it will col.- lect two whole sheets and simultaneously fold thesame through the rollers or pulleys 4O 41.

The rotary folder is then adjusted so that it shall operate at eachsecond revolution only of the carrier A, which may be done by removingone of its blades, as in Fig. 6, or otherwisc, as is described inPatents Nos. 191,494,

197,694, and 214,066, and the rocking tapes 24 are continued inoperation that is, so that the roller 77 will move them up and intocontact with the carrier A, and out of such contact at alternaterevolutions of the carrier. The first full sheet, as X, directed to saidcarrier will make a revolution therewith, during which time thefolding-Blade is inoperative, and receive upon it the next succeedingsheet, as Y, as in Fig. 6, the two lying together upon the'surfa-ce ofthe carrier. During this second revolution of the carrier A the rotatingfolder is brought into operation, so as to protrude its blade 5outwardly, as in Fig. 5, and thussimultaneously double or fold thecollected sheets X Y upon a transverse line and into the nip of therollers or pulleys 4041, from which said collected and folded sheetswill pass outward into the main channel or but they'might be fixed inthe lel with the travel of 'the paper, and the cutfolded transverselythey takeup a length equal to a single full sheet thus folded. It willtherefore beapparent that but one-half the number of sets of suchcollected and folded full sheets,as compared with the number'ofsingle-folded full sheets enter the secondary folding apparatus, andconsequently that only one auxiliary conductingcl1annel or pathway forthe second sheet manipulating apparatus will be used, and this may beeither one, also, that one vibrating folding-blade may be omitted orthrown out of action. M

As shown in Fig. 6, the switches 42 are con tinued in operation, for thereason that they are raised, as in Fig. 2, at the proper time, to causeall of the collected and folded sheets'to pass through the first channelor pathway, the entrance towhich is controlled bysaidswitchcs; positionshown in Fig.2, if desired.

a The apparatus above described is applicable to fold the sheets of anordinary newspaper, in which the columns of printed matter run acrossthe machine. In this case the single sheet might represent a two-pagesupplement,the double sheet represent a four-page or folio sheet, and aquadruple sheet represent a quarto sheet cut apart'at the head, and

the folding above described would be appropriate for such sheets. If theprinting'aud folding machines were made of double width, two such sheetscould be printed and folded side by side, or rather end to end.

, In the modifications shown in Figs. 7 to 11, and now to be described,it maybe supposed that the columns of printed matter runparalting-cylinders to be of but half the diameter of the type-cylindersand contain but a single cutting device. The sheets enter the series offaster-running tapes 22 23,which, in this case, are not provided withnipping-rollers, and

'pass directly onto the carrier A, that is provided wit-h means forcollecting sheets thereon, as is described in Patent No. 213,793, theguides 13 being given the form of switches, as shown in said figures andautomatically vibrated at suitable intervals by means of a rock arm, 3,and a rod, 17, that is suitably vibrated by a cam, 35, (see Fig- 8,)said switches, like the guides 13, entering circumferential grooves inthe carrier A when rocked forward. In

" this modification the train of gear-wheels between the carrier A andthe cutting-cylinders of said roller or mile 7'1 is su Jlied with a l 3l l gear-wheel meshing with the toothed wheel 103. a p

The guidesor'switches'13 are elongated,- so as to form a portion of themain channel or pathway leading to the secondary apparatus,

" which is continued to the pulleys 46 by stretching the tapes 27 overpulleys 36 to the pulleys 46, thence downward to the pulleys 114, saidtapes between the pulleys 46 and 114 taking the place of the conductor62.

The switches 42 are now rocked to alternately occupy the position shownin Figs. 8 and 10. In the latterposition they continue the main channelor pathway beyond the pulleys 38,whereit is formed by a set of lowertapes, 29, that run from pulleys 47 over pulleys 48 under pulleys 99,

thence outward over" the folding-rollers 51 52,

returning under thepulleys 98 and over pulleys 54, with which tapes anupper set, 32, co-operate. This set 32 run fromthe pul- Above theswitches 13 and tapes 27 are conductors 100, a that bridge the spacebetween the pulleys 90 1 and pulleys 37. 1 slightly changed in form, soas to control the entrance-mouth of the first auxiliary channelorpat-hway, which is between the pulleys 46 3,8 in this modification,said switches being leys 37, undertheipulleys 38, overthe pulleys 47,over the pulleys 48, and return around thepulleys 99 and over thepulleys 59.

WVith the tapes 27 conductors 63 coact to form the first auxiliarypathway, while the second auxiliary channel or pathway isformed by thetapes 29 32.- In this modification tapes con-' stituting the auxiliarypathways are given the speed of operation imparted to the carrier A byconnecting the wheel 111 through the intermediate112 with the toothedwheel 121, for the size of the wheel 111 is just twice that of thecarrier, and it makes one-half as many revolutions in Fig. 7. In thismodification the counter-shaft 93. is placed a littlehigher in themachine, and its movements are communieated to the folding-rollers 5152, and vibrating folding-blades from a second transverse shaft, 150,through the -equal toothed wheels 151 152. The change gear-wheels 115116, of equal size, and 117 and 118 the former half the size of thelatter, areused,as has been hereinbefore explained. Other devices notagain explained are the same as are embodied in the precedingdescription, as their like characters of reference indicate. Inoperating upon single sheets this modified apparatus has its guides orswitches 13 secured with their points entered into the grooves in thecylinder A, as in Figs. 2, 7,, and 11, whereupon each sheet directedtothe carrier Awill be guided therefrom out into thesecondary apparatus,the switches 42 operating to direct each alternate sheet into adifferent pathway, so that I blades may be placed at right angles to thehas been heretofore explained. In this operation the secondarysheet-manipulating mech anisms havebeen drivenby equalsizedwheels 115116, as in Fig. 7. To adjust the mechanisms to operate upon doublesheets, the equal-sized wheels 115 116, that operate the switches 42,the tapes, foldingrollers, and folding-blades of the secondaryapparatus, are changed for a pair, 117 118, as in Fig. 8, that will makethese devices work at but half their former speed, the smaller of thesecarrying the cam 85, that operates the guides or switches 13, so thatthey oscillate and cause the collection of two sheets on the carrier A.The pairs of sheets thus collected will be guided by such switchesoutwardto the secondary sheet-manipulating apparatus, where they will befolded, as has been explained with respect to single sheets, but atwhich time the operation of the secondary apparatus, which has but halfthe number of separate sheets to operate upon, isrun at a half-speed, oronly at such velocity as is required by the work it is to perform.

It is to be understood that the folding-rollers 51 52 and their coactingvibrating foldingposition in which they are shown herein, so as toimpart the foldings to the sheets in the other direction, that one blademay supplant the two blades 71, and that the rollers 51 52 may be twosets or one set elongated; also that the gages 66 may be omitted, ifdesired, or any other form of sheet-controlling devices or means forproperly registering a sheet over folding-rollers may be employed.

It will be manifest from the foregoing description of this deliveryapparatus, that it may be modified so as to operate upon sheets, partsof sheets, and sheets multiplied in number, so as to produce greatvariety of products or folded papers by the operation of oneorganization of mechanisms, by slight adjust ments of the parts thereof,and that by the use of change gear-wheels between the primarysheet-manipulating mechanisms and secondary sheet-manipulating f'mechanisms, the great advantage of causing mechanisms to simply run atthe speed required by the work they are to perform may be attained.

Having thus described my invention, what I claim is 1. The combination,with a primary sheetmanipulating apparatus, consisting of a carrier, asA, which is provided with means by which it is capacitatedto guide orfold the sheets, of a secondary sheet-manipulating apparatus, to whichthe sheets are delivered from the carrier A and folded, of interchangeable gearing, whereby said secondary apparatus is driven at the same ora lesser speed than the primary apparatus, all'substantially asdescribed. I

2. The combination, with a primary apparatus adapted tofold sheets, of asecondary apparatus adapted to fold the sheets delivered I from theprimary apparatus, means for rendering the folding mechanism of theprimary apparatus inoperative, means for guiding the sheets therefrom,and means for varying the speed of the secondary apparatus, allsubstantially as described. V

3. The combination, with a primary apparatus adapted to fold andassociate and fold sheets, of a secondary apparatus adapted to fold thesheets delivered from the primary apparatus, means for rendering theassociating and the associating and folding mechanisms ot' the primaryapparatus inoperative, means for guiding the sheets therefrom, and meansfor varying the speed of the secondary apparatus, all substantially asdescribed.

1. The combination, with a primary apparatus adapt-ed to associatesheets, of secondary apparatus adapted to fold the sheets delivered fromthe primary apparatus, means for rendering the associating mechanisminoperative, and means for varying the speed of the secondary apparatus,all substantially as described.

5. The combination, with a pair of foldingrollers and a carrier providedwith a folding blade coacting therewith, of a switch or guide, as 13,and means for adjusting the same so that it may be arranged to guide thesheets off from the carrier and permit their being folded, or be removedto admit the operation of the folding-blade, which latter is providedwith means for'rendering it inoperative, all substantially as described.

6. The combination, with the primary sheetmanipulating apparatus,consisting of the cylinder or carrier A and its appurtenances, and thesecondary sheet-manipulating apparatus, of the main sheet channel orpathway and two auxiliary sheet channels or pathways leading atdifferent points therefrom to the said secondary manipulating apparatus,all substan tially as described. 7

7. The combination, with the primary sheetmanipulating apparatus,consisting of the cylinder or carrier A and its appurtenances, and thesecondary sheet-1nanipulating apparatus, of the main sheet channel orpathway and three auxiliary sheet channels or pathways leading therefromto said secondary sheetmanipulating apparatus, all substantially asdescribed.

8. The combination, with the primary sheetmanipulating apparatus,consisting of the cylinder or carrierA and its appurtenances, and thesecondary sheet-manipulating apparatus, of the main and auxiliarysheet-conducting pathways and switches governing the passage of sheetsfrom said main pathway to the auX- iliary pathways, all substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
